vIMIPRUYIEMElN'I.' IN SIR'UP-DIBPENSING- APPARATUS.

The Schedule referred t in these Letters. Patent and. making part of the same.

To all whom it may concern:

Be it known that I, J oHN MATTHEWS, Jr., of the city, county, and State of New York, have invented a new and useful Improvement in Apparatus for Dispensing'Sirnps and other liquids, of which the following is a full, clear, and exact description, refer-- ence being had ytothe accompanying drawing, forming part of this specification, and which represents a longitudinal or vertical section ot' an apparatus for dispensing sirups and otl'ierliquids, lconstructed in accordance with my invention. f

Whilevapplicable to dispensing Various liquids, -it

will suicehere to describe the invention as applied'.

to dispensing sirups for mixture with soda-'water and other like beverages.

The general principle upon .which my inventionA operates isthat alleged .to have been discovered by Torricelli, in which liquid contained 'in atnbe, closed at the top, but open at the bottom, is supporte'd'or restrained from escaping by the pressure Soif the ont side atmosphere, as against the, weight of the column and partial' vacuum above said column or liquid in the upper portion oi' the tube, vand whereby an equilibrium is established.

Taking this principle as a basis, my invention oonsists in a c ombiuatiomfwith` such tube or vessel, of an air-compressing'audexhaustingdevice' applied .to or connected with the lupper portion of'the tube, and a trap lit-ted to the latter, at or ucar its bottom, so that on workingthe air-controlling device 4at top of the tubeor vessel, tocompress the air within said vessel, the equilibrium between the inside audoutside pressures is broken or destroyed, and a portion of the' liquid contained in,ythe tube or vessel discharged through the trap, yand', on allowing saidl dev-ice to perform its exhausting 1 function, air. is caused -to rush through the liquid, 1o restore the equilibrium, the trap 'being a necessary adjunct in or to the apparatus, to secure to it its proper actioruand serving to prevent dripping or waste. v

Referring to 'the accompanying drawing- A represents a tube or vessel for dispensing sirups for mixture with soda-water or other like beverages. The tube, vessel, or reservoir, may be made of glass, or any other suitable material, and of any desired length, size, and shape.

Said tube is hermetically sealed at the-top, by means oi' a rubber hollow bulb, B', fitted at its lower and open end around a nozzle, a, which establishes communica-tion between the interior ofthe bulb and upper portion of the vessel, and may be secured to or in the lat-ter by passing it through a cork, b, applied to an upper neck, c, of said vessel.

Communicating with -the bottom of the tube A, referably through a lid, d, fitted over a rubber pack'- ing, e, arranged around a neck or month, j, -is a bent ,tube or trap, C, of a double-reversed U-shaped or "other suitable form.

The vess'eiA may be partially filled with sirup by inverting it and removing the lid d for such purpose,

when,.`on again putting on said lid, yand holding the4 vessel in avertical. position, with itsmouth fdownward,1a certain portion ofthe sirup will be discharged through the trap C, till the descent of `the column .causes a partial .vacuum to be established within the upper portion ofthe tube above the sirup, which pro- 'dnce's an equilibrium between the contents of the veslsel and outside atmosphere. This temporary or primary dischargeofsirup may, however, be materially checked by collapsing the bulb B, and holding it compressed during the/insertion of the sirop into the vssel, as, on afterward relaxingthe bulb, the air will be rarefed above the\sir11p,to aid in supportingr the column. But in whatever way the equilibrium is first' established, the after dispensing-action of or from the vessel remains permanent and uniform, and so that vthe sirup may bedischarged n spirts or jets, as required, either in iixed and measured or variable quantities, accordingly as the bulb B is wholly or only partially compressed. Thus the compression of the bulb '13, by theJ hand, serves to displace the air within it,

and-b)1 condensing the airV in the vessel above the sirup, Ito destroy the partial vacuum in the upper portion otf the tube or vessel, and cause a certain amount of sirup to beA expelled or discharged from the trap O; but, on releasing grasp of the bulla-and allowing it to spring back or relax, a partial vacuum above the sirup is again restored, and this, by the momentumxof the column-in discharging, slightly in excess of what is necessary to vsupport the column, so that a small .quantity of fair rushes 'through' the trap O, and up through the liquid, till the equilibrium is restored, and'in the column adjusting itself Within they vessel, the delivery-end `or'portion. ofthe trap C is relieved of sirup, .which prevents all dripping or waste. A sirup or other liquid-dispensing apparatus, constructed to operate asl desciibechis not 'only cheap; simple, and-efficient, but may be rapidly and easily worked. In makingv such apparatus,it will be obvious that a piston, under control of a spring, may be substituted for the elastic bulb B, and a cup-form of trap for the bent pipe C, without changing the character of the invention.

`What is here claimed,`and desired to be secured by Letters Patent, is

The combination of the trap C, tube orvvessel A, and flexible bulb or piston-like device B, all 'arranged for operation as shown .and described.A
